HAY-STACKER.

Application filed November 3, 1913.

T0 all whom t may concern Be it known that I, CLIFFORD A. FLEMING, a citizen of the United States, residing at Huntsville, in the county of Randolph and State of Missouri, have invented certain new and useful Improvements in Hay-Stackers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

'Ihis invention relates to loading and unloading, and more especially to means for stacking or piling hay; and the object of the same is to produce improved means for applying power to raise-the stack of hay.

rlFhis and other objects are carried out by constructing the stacker in the manner hereinafter more fully described and claimed, and as shown in the drawings wherein- Figure l is a perspective view of this entire device ready for use, and Fig. 2 is a side elevation showing the head as raised. Fig. 3 is a detail on an enlarged scale showing the connection between the A-frame and pole, the parts being in section; `and Fig. 4 is an enlarged side elevation of the spring.

In the drawings the letter B designates broadly a base to which is pivoted a stacker frame F carrying the usual or any preferred type of head H, P is a pole also pivoted to said base and connected with the head through the instrumentality of an A-shaped frame A which also is pivoted on the base, and It are the ropes or block and tackle ,mechanism for moving the pole. 'Ihese parts will now be described separately.

The base B is composed of a pair of runners 1 or it might be a wheeled frame if desired) having loops or eyes 2 at their extremities to which a whiiiletree maybe attached for drawing the stacker over the ground, and these runners are suitably connected by cross bars 3 and 4 braced as at 5 so that as light a structure is built up consistent with its considerable size as possible, and the whole by preference lies close to the ground. j

rIhe stacker frame F consists of a pair of side bars 10 pivoted at one end as at 11 to the base, a second pair of side bars 12, loops 13 and 14 secured respectively to the bars 10 and 12 and each loop'embracing one of the other bars so that the latter are telescopically or slidably mounted on each other, pins 15 passing through holes 16 in the bars to hold Speeication of Letters Patent.

them in adjusted position, `and braces 17 leading from the outer bars 12 to the head.

The stacker head I-I consists of cross bars 20 and 21 to which the outer bars12 and the braces 17 are attached in any suitable manner, and longitudinal fingers 22 and lateral fingers 23, the latter connected by a cross bar 24 and pivotally mounted as at 25 on the longitudinal lingers. rIhus is produced a movable structure comprising the lateral lingers and the bar connecting them, and braces 26 project rearwardly from these fingers and are pierced with a number of holes whereby they are adjustably bolted to the bars 12. Each of the latter is connected with the upper end of the Ashaped frame by a longitudinally adjustable element comprising a lower member 28 of strap iron pivoted at 27 to the arm 12 and having its upper end. turned aside as at 28 and pierced with an eye, and an upper member 29 which is a rod connected at its upper end with the frame A, its body passing through said eye, and its lower end turned aside into an elbow 29 which passes through one of a number of holes in the member 28 and receives a nut 29". By removing the latter and withdrawing the elbow and inserting it in one of the other holes, the length 0f this element may be adjusted as desired. Y

The pole P is pivotally supported in a yoke 30 mounted on the rearmost cross bar 3 and rises therefrom to a considerable height--greater, in fact, than the height of the .tl-shaped frame A. On account of its length it is by preference braced by a truss 31 on its forward side, as shown. Near its lower end it carries a spring 32, whose upper extremity is connected by a rope 33 with the head I-I, and a chain 34 or like flexible element holds this spring in active position.

The block-and-tackle` mechanism It consists of a pulley 40 connected with the upper end of the pole, a second pulley 41 connected with the center of a bail 42, which in turn is connected to the front cross bar 4, a rope 43 leading from the upper end Vof the pole around the lower pulley and thence upward over the upper pulley, and another pulley 44 detachably connected with one front corner of the base and under which this rope is led before being carried to a distance and attached to a whiiiletree or singletree so that a team or a horse may be employed to raise the stacker as usual.

Ihe A-frame A consists of two side bars l 50 pivotally mounted at-their lower ends on a cross rod 51 within the base B and converging thence totheinupper endswhich nearly meet but are connected by a U-shaped 'i guide 52 through which the pole Pis `Slid- V ably mounted. The bolt 54 which passes.w throughtheends of the .side bars and the` f mally somrewh'atjhelow the upper end of the l Q'pfolevl), andthe Ydisposition of the cross rod r511with"respect,tofthe pivot ofthe pole is suchfthat" when, the latter is drawn down- :as seen in'fFig. 2y the guideand roller at thefupperlendof the A-frame will not "contactfwith the; pulley 40 at the upper end ftallerthanthe frame and the pivotalsuplof therpole;v 'In otherfwords, the. pole is `Vportslofthese two elements' are spaced some '.distancejapart on the base B.

vrl/Yith. this lconstruction of parts, the oper- ;.ationofthe machine is as follows :The base YVwith the superimposed structure being ;dra,wn1 to thepoint of use and probably .stakedto the ground, the hay is drawn to the-stacker orin somemanner thrown onto the longitudinal fingers of the vhead H until Y av considerablev charge is placed e thereon.

Then the vteam or horse is started up and frthe rope draws on the upper end of the pole which at this ytime stands upright as seen in V`Fig. 1;,with the result that the pole moves l fromithis; position. rearward vand downward-traveling over the roller .at the head ofthe Affr'ame which latter also turns on its ,pivot.- They guide keeps the parts 4in relative'position near ytheir upper ends, and the rtension of the Vrope draws the poleV con- Y 'sta'ntly yagainst the-roller so that the advanta'gerofpdisposing the pole forward of the A7fframe` rather than to the rear of it as is common, will he obvious. At the beginning of, the upwardmovement of the load on the head H, said load is lifted almost vertically 55, rbars ,l0-12, and as the stacker frame swings .because `of the length of the combined side around its/pivots 11the weight of the load is ,thrown more and more' onto them and V'j v.the/force necessary-to lift it becomes less and nshown in Fig. 1 through a path'to th'e rear less.l HThe -pole moves from the position vand ,carries the iAfframe with it, the tele- Vlscopic rodsconnecting the upper end of the A-frame with the head H and raising said ahead Vin a manner which will be clear.

Finally the parts reach the position shown in Fig. 2 and the rope R draws on the spring 82 ,to check the further upward movement of the head. This occurs rather suddenly so that the load of hay on the head is tossed off of it onto the stack bein'gformed. rlhe horse is then backed and `the head lowered to its original position for i11,.the side barsj10-12 are adjusted over each other as their loops 13-14 will permit,

-and finally the pins`15 are inserted in the proper holes to hold them when adjusted.

f Meanwhile the telescopic rods S28-29 will also be adjusted in a manner which will be clear.Y To store the device in small space these adjustments are also useful, and they will doubtless be employed before dragging the stacker back to the barn or other place of storage. The parts are' by preference made as far as possible of wood, with metal for the hardware, either of galvanized iron or suitably treated to prevent rust. I do not wish to be limited to the proportions of parts, nor in fact to the strict details of construction. I find the loop or bail on the forward cross bar t to be of advantage because it throws the strain of the rope mechvanisin R onto two points .within the length of this cross bar, and therefore permits the latter to be made of lighter `lumber than if thestrain were all thrown onto the -center of it.v The most important feature of this invention, however, consists, in my opinion, of the .disposition of theilong pole P forward-of the A-frame A, the pivoting of it atrits lower end on the base B, connecting the rope mechanism R with its upper end, and the mounting of a roller and guide in the top of the frame so that the pole travels within this guide and over the roller as the yload is lifted. Especially do I consider it of advantage to dispose the pole forward of theV A-frame rather than in lrear of it, and to space the pivots or supports at the bottom of these elements so that the frame turns about a center or pivot which is different from thatof the pole. Iiind by experience that one horse will lift a considerable load on the head H when the mechanism is constructed as has been shown and described, and yet the stacker frame is adjustable to quite small compass so that the entire device can be stored in an ordinary barn.

What is claimed as new is:

1. In a hay stacker, the combination with a base, a stacker frame pivoted at one end thereto, and a head carried on theother end of the frame; of a cross bar near the forward end of the base, a pole pivotally mounted at its lower end on said cross bar, rope mechanism connected with the upper end of said pole, an A-shaped frame pivoted on the base iny rear of said cross bar and pole, a

roller carried on the front face of said frame and over which the rear edge of the pole travels, means for holding said pole in engagement with said roller and permitting it to slide freely relative to said frame and connections between the upper end of said Ashaped frame and the stacker head.
